Yes, Mega Man was on the Genesis
There’s been a Genesis-styled chiptune cover of some Mega Man music making the rounds on the Internet, which has been making people ask, “What if Mega Man was released on the Genesis?” Well, it was! Rockman: Mega World was released in late ‘94 for the Mega Drive in Japan and was released in ‘95 as Mega Man: The Wily Wars in Europe and Brazil.
The game was an upgraded compilation of the first three Mega Man games. It never received a physical release in the US, but was available on Sega Channel, the satellite service.
All versions of the game are collectible, going for at least $250. Don’t be fooled though. Any physical copy you see with Genesis branding is a reproduction and is worth about $40, not the three digit prices you’ll see on eBay.
